UNLoADER Foa eoNvEYnns.

To all whom it may concern.' n

Be it known that I, ANTON BnoTz, a citizen of the United States,residing in Sheboygan, in the county of Sheboygan and State 'ofWisconsin, have invented new and useful Improvement-s in Unloaders forConveyers, of which the following is a description, reference 'being hadto the accompanying drawings, which are a part of this specification.

This invention relates to improvements in nnloaders.for conveyers andmore part-ieularly to devices for unloading material from beltconveyers.

It is Qneiof the objects of this invention to provide an unloader forconveyer belts which may be adjusted to unload a portion of or all ofthe material conveyed by the belt.

A further object of the invention is to provide aconveyer belt unloadingapparatus in which a plurality of unloaders may be positioned alongsideof but at different points of a conveyer belt to discharge apredetermined amount of the material at said difierent points.

A further object of the invention is to provide an unloader forconveyers which may be actuated by frictional contact with the. conveyerbelt and by the-material car' ried thereby.

A further object of the invention is to provide an unloader forconveyers which is in the form of a disk adapted to roll sidewise on thesurface of the belt and beneath the material carried thereby.

l/Vith the above, and other objects in view, the invention consists ofthe unloader for conveyers and its parts and combinations set forth inthe claims, and all equivalents thereof.

In the accompanying drawing in which t-he same reference charactersindicate the same parts in the several views Figure 1 is a plan view ofthe complete unloader shown in connection with a conveyor belt and inthe operation of discharginga portion of the material carried by thebelt; Fig. 2 is a side view thereof; Fig. 3 is a transverse sectionalview: and Fig. d is a diagrammatic plan View of two of the unloadersshown unloading material from a belt at different points.

Referring to the drawing the numeral 8 indicates a conveyer belt ofordinary construction which is adapted to convey the ma- Speccation ofLetters Patent.

terial 9 on the upper surface of its upper portion. 'The belt issupported on upper rollers l0 and lower rollers 11. A discharg disk 12extending over the upper portion o1 the belt and one or more upperrollers and engaging the upper surface thereof is carried by a verticalshaft 13. The shaft is journaled in the arms 14 of the swing frame 15and the swing frame is supported by and has its bearing in the standard16 positioned alongside of the conveyer belt 8. The lower end of thevertical shaft is pointed and rests on top of an adjusting bolt 17threaded in the lower arm to provide for adjusting the disk withrelation to the belt. The swing frame 16 which may be swung horizontallyto have the disk overlap the belt more or less is held in adjustedposition by means of bolts 18 threaded in the standard 16 and enteringthe apertures 19 provided in the swing frame 15.

In order to discharge t-he material from the disk a delecting plate 20is adjustably connected to the upper arm 14 of the swing frame anddepends downwardly therefrom at an angle and its lower edge ispositioned to just clear the upper surface of the disk and to deflectmaterial olf the edge of the plate. The deilecting plate is providedwith an upstanding slotted arm 21 and a bolt 22 extending through theslot and threadedinto the upper arm 14 serves to adjustably connect thedeflecting plate to said arm.

In the operation of the unloader as shown in lligs. l, and 3, a portionof the material carried on the belt will slide on the edge portion ofthe disk and the frictional contact of the disk with the belt and thematerial will impart movement to the disk and the disk in rotating willcarry the engaged portion of the material off the belt. When the portionof the disk carrying the material passes beneath the deflecting platethe said plate will deflect said material oil' the edge of the disk andas the material is continuously fed to the disk the operation will bepractically continuous.

-lt is to be understood that the portion of the material which is beyondthe plane of` movement of the disk shown will be engaged by one or moreother similar unloading devices with the disks thereof overlapping theconveyer belt to a greater extent than the disks shown.

F ig. L1 indicates a belt being unloaded by 110 -to be understood thatconveyer belt, said i With the belt to permit the material to becarriedthereby and unloaded at other points.

While the disk is shown as .rotated by trictional Contact with the beltand the material itinay be desirable in some cases to positively rotatethe disks by a belted or geared source of motion and it is thespecification and claims contemplate unloaders operating in .thismanner.

AFrom the foregoing description it Will be seen that the unloader isvery simple in construction and operation and may be adjusted todischarge all or a portion of the material carried by the belt at onepoint or at a plurality of points.

What I claim as my invention is:

1. An unloader for a conveyer, consisting of a revoluble disk journaledin a support and positioned to overlap a conveyer b'elt to receivematerial thereon to remove material carried by the belt.

2. An unloader for a conveyer, comprising a support, a frame adjustablycarried thereby, and a revoluble disk journaled in the frame andpositioned to overlap a conveyer belt to receive material thereon toremove material carried by the belt.

3. The combination with a conveyor belt, of unloading means therefor,consisting of a plurality of disks jonrnaled in supports located atdii'erentpoints alongside ot a disks overlapping the disk overlappingconnection With a belt and each succeeding,`

V the belt to a greater extent than the preced- 'inw disk to removematerial from said belt.

4. rI he combination with a conveyer belt, of unloading means therefor,comprising a plurality ot' frames adjustably located at different pointsalongside of a conveyer belt',

and disks journaled in said frames and positioned to overlap the belt,each succeeding disk overlapping the belt to a greater extent than thepreceding disk to remove material from said belt.

5. The combination with a conveyer belt, of unloading means therefor,comprising a plurality of supports located at different points alongside'of a. conveyer belt, frames adjustably connected to arranged to beswung in a horizontal direction, and disks journaled in said frames andpositioned to overlap the belt, each succeeding disk overlapping thebelt to a greater extent than the next preceding disk to remove materialfrom said belt.

6. The combination with a conveyer belt, of unloading means therefor,comprising aplurality ofsupports points alongside of -a conveyer belt,frames adjustably 'connected to arranged to be swung in a horizontaldirection, disks journaled in said frames and positioned to overlap thebelt, each succeeding disk overlapping the belt to a greater ex- -tentthan the next precedingA disk to remove material Vfrom the belt, means`for adjusting ,the height of the disk with relation to the belt, and adetiecting plate adjustably earried by the frame and positioned todeiiect the material ofi of the disk.

7 An unloader for a conveyer, comprising a support, a frame swinginglycarried thereby and provided with projecting arms, means for locking theframe in a xed position, a vertical shaft journaled in the arms, meansfor adjusting the shaft vertically, a

-disk carried by said shaft, a detlecting meniber carried by the frameand extending above the disk, and means Jfor adjusting the verticalheight otl said delieclini,r member.

ln testimony whereof, l athx my signature, in presence of tivowitnesses.
